To all whom it may; concern:

lie it known that '1, MARTIN NILLIAM Moons, a citizen of tnc UnitedStates, residing at Springfield. in the county of Banga- 111011 andState of Illinois, have invented certain new and useful Improvements inAcetylene-Gus'iiainps; and I do declare the a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it uppert-uins to make and use the same.

This invention relates to improvements in acetylene lamps.

(l ne object. ot the invention is to provide a lump of this characterwhich'is particularly adapted for the use of miners and which isprovided with an improved construction and arrangement of feedingmechanism whereby the water from the ervoir of the hump iscontrollecl'and discharged into the generating chamberin the desiredquantities.

With this and other objects in view, the invention consists of certainnovel features of construction, and the combination andarrangement ofparts as will be more fully described and claimed.

1n the accompanying drawings; Figure l is a central vertical sectionalview of my iniprovcd lamp; Fig. 2 is'a horizontal sectional viewthereof, taken on the line 2--2 of Fig. 1; Fig. 3 is a detailperspective view of the supporting plate for the perforated waterdistributing cup of the lamp.

My improved lamp comprises a base section 1 which contains the carbidand forms the gas generating chamber of the lump. The base section 1 isthreaded cxteriorly at its upper end and onto said threaded portion isscrewed a gas chamber 2 which is in the form of an inverted cup and hasits sides bent outwardly to form radially disposed annular recess 3. Thelower end of the mp2 forming the gas chamber is threaded inte'orly as 1and is adapted to be down onto the threaded upper end of the basesection 1. in the annular recess 8 of the chamber 2 and engaged with theupper edge oi the base section 1 is a gasket 5 and between the gasketand the upper wall of the recess 3 is clamped the outer edge of a gasfiltering screen 5 which extends across and covers the lower end of thechamber 2 as shown. The gasket 5 forms a gas tight connection betweenthe chamber 2 and the upper end of the generating chamber formed by thebase '1.

Secured to and having a fluid tight engagement with the sides of thecap-forming the chamber 2 is a water reservoir 7 indie upper end ofwhich is arranged-a filling opening 8 normally closed by a screw plug 9as shown. Secured to one side of the lower portion or" the waterreservoir 7 is a reflector 10 and arranged through the lower portion ofthe reflector and through theudjacent sides of the reservoir 7 and gasclrambcr2is a gas discharging tube '11 in the outerend of which issecured a burner 12.

Arranged in the bottom of'the base section or generating chamber 1 ofthe' lar'np is a cup supportingplate 13 having thereon a centrallydisposed I upwardly projecting cir cular boss'ld which ispreferablystruck up i'roin the-plate 13 as shown. =Engaged but detaohablyconnected with theiboss when the plate 13 is a perforated waterdistributing cup 15 which projects. upwardly to a suitable distance inthe generating chamber. Arranged in the center of the reservoir 7 andextending downwardly through the cap 2 forming the gas chamber andhaving its lower end projecting into the water distributing cup to apoint near the lower end thereof is a water conducting tube 16 in thelower end of which is formed a tapered valve seat 17. In the tube 16adjacent to the bottom of the reservoir 7 or upper side of the cap 2 arewater discharging passages 18 of which there maybe any suitable numberand through which the water from the reservoir 7 discharges into thetube 6.

The upper end of the tube 16 is closed and has therein a threadedpassage 19 with which is engaged the threaded upper end of a valve stem20 which is disposed in the tube 16 and has on its lower end a conicalshaped valve 20 which is adapted to be engaged with the seat the tubewhereby the latter is opened and closed to permit the discharge of waterfrom the tube into the distributing cup 15. The water when thusdischarged into the distributing cup 15 passes through the dischargeopenings therein onto the carbid in the lower portion of the generatingchamher. The water in discharging apertures in the cup 15 will be evenlydistributed onto the carbid and by PI'OVldlIlD' the valve 21 as hereinshown and described 17 in the lower end of.
